2+cotA=1 homework help

Alex Ar [27]

$2+\cot A=1\implies \cot A=-1\implies \tan A=-1$

This happens whenever $A=\dfrac{3\pi}4$ or $A=\dfrac{7\pi}4$ . More generally, $\tan A=-1$ whenever you start with one of these angles and add any multiple of $\pi$ , so the general solution would be $A=\dfrac{3\pi}4+n\pi$ , where $n$ is any integer. (Notice that when $n=1$ , you end up with $\dfrac{7\pi}4$ .)

lana [24]

Answer:

5.099*10^14 m^2

Step-by-step explanation:

Earth is in thermal equilibrium. This means that our planet is radiating away exactly as much energy as it is receiving from the Sun. This "re-radiation" from the Earth is not visible because it its peak wavelength is in the infrared part of the spectrum. Even the coldest parts of the Earth are way above absolute zero, so every square meter of Earth’s surface is radiating this energy out to space. Using the same radius given in step 2 above, and the formula for the area of a sphere, calculate the surface area of the Earth.

(The radius of the Earth is 6,370,000 meters.)

The earth is spherical in shape , so we use the formula for finding the surface area of a sphere

Surface Area= $4\pi r^{2}$

S.A=4*3.14*6,370,000^2

S.A=4*pi*40576900000000

S.A=5.099*10^14m^2

Identify the value that is NOT in range of the piecewise function. A. -3 B. -2 C. 3

Blizzard [7]

Answer:

Option A i.e. y = - 3 is not in range of the piece wise function graphed.

Step-by-step explanation:

The range of a function y = f(x) is given by the possible values of y for the possible domain (x-values) of the function.

Now, it is clear from the graph of the function that the value of y never goes below y = - 2.

The graph is drawn in such a way that any value of y less than - 2 and greater than - ∞ is not in the range of the function.

Therefore, option A i.e. y = - 3 is not in range of the piecewise function graphed. (Answer)

Which function below has the smallest slope?. A Graph with a line going through -5 on the Y Axis and Postive 2 and a half on the

Allushta [10]

The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.
